Putting on sterile gloves correctly comes down to one core principle: your bare skin only touches the inside of the gloves, and the sterile outer surface only touches other sterile surfaces. Every step in the process exists to protect that boundary. Once you understand the logic, the technique becomes intuitive.
Start With Clean, Dry Hands
Sterile gloves go over clean hands, not instead of hand hygiene. Wash with soap and water for at least 15 to 20 seconds, covering all surfaces of your hands and fingers, then dry thoroughly. Wet or damp skin makes gloves harder to pull on and increases the chance of tearing. If you’re using an alcohol-based hand sanitizer instead, rub it over all surfaces until your hands feel completely dry, which takes about 20 seconds.
For surgical procedures, a more extensive scrub is required. You’ll wash your hands and forearms for 2 to 6 minutes, depending on the product’s instructions. Longer scrub times (like 10 minutes) are no longer considered necessary.
Choose the Right Size
Sterile gloves are sized by number, typically ranging from 6.0 to 9.0 in half-size increments. To find your size, measure the circumference of your dominant hand around the knuckles (excluding the thumb) with a tape measure. That measurement in inches roughly equals your glove size: a 7-inch hand needs a size 7 glove, an 8-inch hand needs a size 8.
Fit matters more with sterile gloves than with standard exam gloves. A glove that’s too large compromises your dexterity and can slip. One that’s too tight restricts movement and tears more easily. If you’re between sizes, go with the larger one.
Open the Packaging Without Contaminating the Gloves
Sterile gloves come in two layers of packaging: an outer peel-away pouch and an inner folded wrapper. Start by peeling open the outer pouch and sliding out the inner wrapper. Place it on a clean, flat surface at about waist height.
Now open the inner wrapper by unfolding its flaps. This is where people often make their first mistake. The gloves are resting on the inside surface of this wrapper, so you can touch the outer edges and corners of the paper, but not the area where the gloves sit. Unfold the flaps away from you first, then toward you, so your arms don’t cross over the sterile field. Once open, you’ll see the right glove on the right and the left glove on the left, palms facing up, with their cuffs folded outward.
Put On the First Glove
Pick up the first glove (most people start with their dominant hand) by grasping the folded-over cuff with the opposite hand. You’re touching only the inner surface of the cuff, the part that will end up against your skin. This is the key rule for the first glove: your bare hand never touches the outer, sterile surface.
Slide your hand into the glove with your fingers pointed downward. Push your fingers into the finger slots and pull the cuff toward your wrist using the same hand that’s holding the inner cuff. Don’t try to get the cuff perfectly positioned yet. It’s fine if it stays partially folded. You’ll fix it after the second glove is on.
If the glove doesn’t slide on smoothly, resist the urge to grab the outside of it with your bare hand. Instead, pinch the inner palm surface of the cuff and gently pull it further onto your hand.
Put On the Second Glove
The second glove follows a different rule. Your already-gloved hand is now sterile on the outside, so it can touch the outer surface of the second glove, but your bare hand still cannot.
Slide two to four fingers of your gloved hand under the folded cuff of the second glove, gripping it from the outside. Lift the glove up and away from the wrapper. Slide your ungloved hand into the opening, pushing your fingers into position. Your gloved fingers stay tucked under the cuff the entire time, pulling the glove up and over your wrist and forearm.
Now you can go back and fix the first glove’s cuff. Use the fingers of your second (now gloved) hand to slide under the folded cuff of the first glove and unfold it into place. Since both hands are gloved, sterile surface is only touching sterile surface.
Keep Your Hands in the Sterile Zone
Once both gloves are on, hold your hands in front of you, above your waist and below your chest, with fingers interlaced or held together. This zone, roughly between your waist and mid-chest, is considered the sterile area. Dropping your hands to your sides, touching your face, or reaching behind you breaks sterility, even if you don’t touch anything visibly dirty.
If you touch any nonsterile surface at any point, the gloves are compromised. The fix is simple but non-negotiable: remove both gloves, perform hand hygiene again, and start over with a fresh pair. There is no way to re-sterilize a contaminated glove, and the CDC explicitly states that gloves should never be washed for reuse.
Common Mistakes That Break Sterility
The most frequent error is touching the outer surface of the first glove with your bare hand while putting it on. This typically happens when the glove is tight and you instinctively grab the outside to pull it into place. If the glove feels too snug, check your sizing rather than forcing it.
Another common mistake is contaminating the inner wrapper when opening it. Reaching across the sterile field, letting the wrapper’s flaps snap back onto the gloves, or setting the wrapper on a wet or dirty surface all compromise the gloves before you’ve even touched them. Open the flaps by pulling them away from the gloves, not over them.
Rushing is the underlying cause of most errors. Sterile gloving is a deliberate process. Each step is simple, but skipping ahead or moving too quickly leads to accidental contact between bare skin and sterile surfaces. Slow, purposeful movements are faster in the end because they avoid the need to start over.
How to Remove Sterile Gloves Safely
Removal follows a “glove to glove, skin to skin” rule that mirrors the logic of putting them on. Grasp the outside of one glove at the wrist and peel it off, turning it inside out as it comes away from your hand. Hold the removed glove in your still-gloved hand. Then slide your bare fingers under the wrist of the remaining glove, touching only the inside surface, and peel it off inside out, enclosing the first glove inside the second. This leaves all contaminated surfaces wrapped inward, away from your skin.
Discard both gloves immediately and wash your hands again. Hand hygiene after glove removal is just as important as before gloving, because microscopic tears in gloves are common and allow bacteria through without being visible.
